These are a really solid AT binding. The binding feels sturdy and well constructed, which I expect from Salomon. The weight more than makes up for the downhill performance. These perform nearly as well as a dedicated alpine binding. I use them at the resort as well as in the backcountry. The hike/ski mode switch can be a little difficult to articulate with a ski pole because the basket can interfere with the operation, but it's a minor inconvenience. The riser works fine for steeper slopes and there's plenty of mobility in the toe to make touring very comfortable.
Just got a pair of these mounted onto some Rocker 2's 122s at a size of 192cm and somehow managed to take the heel piece off on my first day out on them. It was a sick powder day and I had taken about 5 runs on them. I went for a Misty 7 off a ledge and over rotated, landing sideways. One ski ejected properly but the other had the heel pice and brake removed. Made this binding feel less trustworthy for me. I have heard of this kind of thing happening to other people. Not a binding for people who really charge it on the mountain. Stick with the STH 16s.
Last winter, I had a good amount (10 or so) of powder days on these and they are absolutely amazing. I have these mounted on Salomon Rocker 108s and they are good from skiing groomers to hip deep pow. The touring is great on them Slap some skins on and the first few times of touring in them its difficult to snap back in to an alpine binding, but after a couple times they are great!
